Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user process to perform improper GPU memory processing operations to gain access to sensitive kernel information.
This issue affects Valhall GPU Kernel Driver: from r29p0 through r49p5, from r50p0 through r54p3, r55p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r49p5, from r50p0 through r54p3, r55p0.
AnalysisAI
Sensitive kernel memory is exposed to local non-privileged user processes through improper GPU memory processing operations in Arm's Valhall GPU Kernel Driver and 5th Gen GPU Architecture Kernel Driver. The flaw spans a wide driver revision range - Valhall from r29p0 through r55p0 and 5th Gen from r41p0 through r55p0 - covering Mali-G series and Immortalis GPU generations deployed across hundreds of millions of Android and embedded devices. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to execute code as a local non-privileged user on a system running an affected Arm Valhall or 5th Gen GPU Kernel Driver (r29p0-r55p0 for Valhall; r41p0-r55p0 for 5th Gen). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS vector (AV:N/AC:L/PR:N/UI:N) is inconsistent with the description, which explicitly states exploitation requires a local non-privileged user process; the network attack vector and no-privilege ratings are almost certainly erroneous and should be AV:L/PR:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to a driver version beyond the affected ranges per the Arm security advisory at https://support.arm.com/documentation/111552/1-0/?lang=en. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit your device inventory to identify endpoints running affected GPU kernel driver versions (Valhall r29p0-r55p0 or 5th Gen r41p0-r55p0) and contact device OEMs to confirm patch availability and timelines. …
